To all whom it may concern:

Be it known that I, MA'rrHIAs GAR'VEY, a residing 'at Mineville, in the county of Essex and State ofN'ew York, have invented certain new and' useful Improvements in -Apparatus` for Testing Drill-Holes; and I do hereby declare .stricted to such euse.

A :from the direction in w fstarted. It oftentimes becomes a matter of the following to bel a; full, clear, and exact description of the invention,"'such as will venable others skilled in theV artto which it appertains tomakejand usethesame.

My invention relates toapparatusfory testin drill holes and ismore especially intende for testing deeppholes made by `the use of diamond drills, although it is" not re- It' is well known` drillin Adeep holes of small diametenespecially 1f such holes are started at an angleto the perpendicular, that these holes will, aftera-tlme, runV off; that is to `say will incline away vich they were-first high importance to accurately testthe ineliL nation of these holes, especially incase of contiguous mining claims.` .l i

Theobject of my invention isto provide a vsimple apparatus and method by which ering said apparatus into the relpresents a drill h W the inclination of suchV drill holes `may be readily and accurately tested b sim ly'low.-

' drill lible -andallowing it to stay there a delinite time, and with thls object in view myinvention con sists in the method and in the construction and combinations 'of parts as hereinafter described and claimed.

In the-accompanyin drawings- Figure 1 01%)., the lower partof 10h is inclined from the perpendicular, and showing the testing apparatus suspended therein. A Fig. 2 isa vertical cross section of the testing a paratus, the outer casing beinglremoved. 1g. 3 is a cross section sim1 lar toFig. 2, but taken on a plane-at right angles thereto.' Fig. 4 is la partial sectional vview of the same apparatus, showing the position assumed thereby and bythe india eatin needle and compass after an inclinedhole lgias been tested. Figs. 5, 6, 7 and 8 are cross sections on the lines ,5s-5, 6 6, 7 7.,

Vand 8-8, respectively, of Fig. 4, Fig. 8 being on a slightly larger scale.` Fig. 9 is a' `vertical cross section on the line 9-9 of Fig).

Fig. 10 is ayertlcal cross section of a part 'of amodified inclination of vvthe A and ythen this testing operation Visrepeated at every 1(1)0` feet-.downto 'thelnil'ltoinl ofthe p the testing apparatus consists ofl"asolid base .the portiong is.. firmly' form of testing'apparatus, and Figs. 11 and 12 are cross sections thereof taken on th Fig. 10. f Referring to Fig. 1, o:- represents a drill holeand o the caslng' of the testing apparatus, which is adapted to be let down into the hole by a wire c and stopped at any de' sired point. In actual use, the testin apparatus 1s let down, for example, 100 eet,*the

hole being there tested hole. .A Y f Referring especially Ato Figs. 52,31'and' 4,

al, preferably of brass andlargJ ,enough f toj serve as a.y weight to carry4 the 'testing appaf ratus down, even if the holefiswholly' orv partially filled with waterorfoilfg'lh bases 1s cut away and providedwith" a ,fsrew-- 'l5 threaded portion f and astillsialler pl 'i portion g. The bottom of the cette` screw-threaded` (not shown) and.' to engage the screw-threade po" preferably made of brassjorso which will not readily rxist,and provided with two .sets'of op ositely cut away portions land t ese sets, how# ever, belng located at right angles j to each other. The `lower part ofjsthe'casing. h is brazed, orfirmly attached, to the part g in any suitable manner. lc represents a partition located between these sets of erfora-. tions and firmly secured to the cy ln'drical 90- ca'sing '7L by brazingor iniany other suitable manner. m represents another partition secured in the casing le near itsto by means -of pins n, or in .any lother suitale manner,

and provided with a central perforation for lthe passage of. a movable pin o, with a number of perforations `for the passage' of water therethrough, vand with two perforations for the passage ofthe slidable guide bars hereinafter described. 79 represents a cylinder of any material' v which will slowl dissolve in water such as an ordinary stiel; ofl candy. On'the lower end of the piny o is rmly fastened a disk g, `slotted so 'as to slide freely along the 105 guide bars, and provlded .With4 a series of erforations vthrough which water may pass or the` urpose .of attacking and dissolving thecan y cylinder p. y.

afrepresents a vspring located betweenthell partition m and the disk g, which tends to force said disk to its lowest possible position.

a plate o provided with holes for allowing water to pass freely therethrough, and hav- -ing a rectangular extension `w. The part u `extends downwardly nearly to the central part of the casing, and to'its lower end is attached a heavy connecting piece havinO' a curved scale y thereon. At the lower en this connecting piece is provided with a retaining pin 1, which limits the movementof the indicating-pointer, hereinafter described, in one direction. To the lower end of the piece are attached two bars 2 and 3, which curve away yfrom each other, as shown in' Fig. 3, forming an oval, to the lower part of which the pin t is attached. Fastened in any suitable way to the lowerend of the part u, are two bent arms 4. These arms are ,parallel with each other and in their lower ends is mounted a freely revoluble pin 6, to which is attached an indicating pointer 7. 1

8 represents a spring fastened to t-he part u, and which, when the disk v descends, is compressed by said disk, the lower end bearing against the pivot pin 6 and holding the pointer 7 inthe position then assumed by it.

The downward movement of the disk o is accomplished as follows: 9 and 10 representf slide freely in slots provided for this pur' pose in the partitions la and m. These guide ars or yplates are each cut awa as shownl I at 11, and when the disk g is orced down by the spring 1' a certain distance, it engagesfthe shoulders formed on .thes e\bars, forcing them down and therebyforcing the disk o down, thus compressing the sprmg 8 and locking the pointer 7 in the position it happens to be in'at that particular moment. This occurs whenever the stick of candy p is sulliciently dissolved so that it will give way,

releasing the spring r.

Between the curved arms 2 and 3 is mounted a compass supported on pins such as 12, sothat the compass as a whole can move freely between sald arms. This compass is shown in detail in Figs. 8 and 9, and

' it consists of a cylindrical casing 13 closed by a glass plate 14 at the top, and provided with va bottom 15, which is perforated for the passage vof the rods 16 and 17, which are attached to the movable plate 18` below the case 13, and also to a movable plate 19 within said case. Centrally mounted k.on the Below the partition'lc are located the de- Vices for indicating the direction and incliplate 19 4is a pivot pin 20, having an enlarged top 21 and carrying a magnetic needle 22. A spring 23 is interposed be-` tween the bottom of the case and the plate, and 24 represents a disk of alum or other material, which slowly dissolves in water. It is evident from the construction described that as long as the disk 24 is undissolved, the compass and the needle therein will move freely in every direction, the magnetic needle will point to the pole and the compass case will assume a level position. `As soon, however, as the disk 24 dissolves, the spring 23 presses the plate 19 upward, pressing the top 2l of the pivot pin against the glass and preventing any further movement of the magnetic needle 22.

The operation of this form of the device the position 'shown in Fig. 2 with the candy stick p-and the disk 24 in position, the case b is lled with water and inverted and the indicating means dropped into it and screwed home. By means of the wire c, the case b and the parts contained therein are dropped down the hole the desired distance and the apparatus is allowed to stand, say for an hour. If the hole is inclined, the case b will of course occupy an inclined position and the pointer7, not being acted on by the spring` 8, will hang vertically, as indicated in ig. 4. The magnetic needle will, at Athe same time, point north. As soon as the disk 24.has become dissolved by the water in the casing, the spring 23 will prevent the further rotation of the magnetic needle, and as soon as the stick p has been dissolved, the sprin r will force down the disk and the gui e plates 9 and 10, forcing dqown the plate o, which thereby causes the spring8 to strike the pin 6, thus confining the pointer in the position it has assumed. The ap aratus is then drawn up, the case b taken o 1, and readin s taken, the

compass and the 'ointer 7 in icating the exact direction an inclination of the hole. In Figs. 10 to 12, 7a modified form of the 'apparatus is shown, which is used when adapted when holes originallty driven in on an incline are tested. In this form the compass is mounted as before in the lower part of the indicatin and registering apparatus, but is supporte on Apivots in a ring 37, and this ring 37 -is supported on pivots in the casing 25, which corresponds to the casing z in the other form. The casing 25. is provided with a partition 26; this partition is hollowed out as-shown in Fig. 10 and rovided with a concentric scale 27 and a radial scale 28 as shown in Fig. 12, corresponding to and in line with that of the compass. Above this casing and centrally thereof, is

cameos 'i mounted a ball 29 from the lower part of which an` indicating i needle 30 depends.

' This ball 29 is supported on pivots 31 ina ring32, and this rin 32is ,supported on pivots 33 in another ring 34, carrled by the casing 25, the pivots 31 and 33 being at rightnngles to eachother asin an ordinary compass mounting, the eiiect being that the ball 29 is free to rotate .in every direction,

so that thefneedle 30. will always point di-A rectly downward. Above the ball 29, is mounted a sliding plate 35 provided with a depression 36 of a curvature corresponding to that -of the ball 29. This disk 35 is adapted, when it falls, to press upon the ball 29 `and lock it in the position 1t hasv thenassumed. .The lates s rin and ide bars are similar-Ito thbsepalregasdy dczgilded. The operation of this form of device is precisely similar to that already described except that the'needle 30 will, when the apparatus is inclined, swing out'over the two scales 27 and 428, thereby indicating on one the deviation from the'perpendicular and giving on the other the bearing, only when com ared with the compassreading.

ile I have -thus described my invention, I wish it to be distinctly understood that I' do not limit myself to the exact fea` tures shown and described, the main idea of the invention being the rovis'ion. of an apparatus which in a tigh casing can be let down into a drill` hole, and which will automatically set itself accordin to the direction 1 and degree of inclinatlon of said `hole and will Vthen lock itself in such set position, whereupon it' can be drawn up and' read.
